"WebRandom provides an interface to Ruby's pseudo-random number generator, or PRNG. The PRNG produces a deterministic sequence of bits which approximate true randomness. The sequence may be represented by integers, floats, or binary strings. The generator may be initialized with either a system-generated or user-supplied seed value by using ::srand.
